[Pulmonary artery arrosion due to parietal endocarditis--a late complication of a haemodynamically ineffective VSD (author's transl)].

A case of late complication after operative correction of a valvular pulmonary stenosis is reported. Chronic pulmonary embolism secondary to bacterial endocarditis situated opposite to an uncorrected small ventricular septal defect in the right ventricle caused arrosion of the pulmonary artery and subsequent severe fatal bronchial hemorrhage. The relation between VSD and bacterial endocarditis and the surgical consequences are discussed.
